"Unfortunately, earlier this week Greg's condition took a turn for the worse.
"At 8.39pm on Saturday 5th December 2020, Greg left this earth, surrounded by his loving family."
Sutherland had been a police officer for nearly 30 years, spending two years in South Auckland before moving to Christchurch, and then, in 1997, to Twizel for six years and Tekapo for five.
He was stationed in Timaru for 12 years, mostly as a frontline sergeant.
In 2018 he left police for a new career as a funeral director at Timaru's Aoraki Funeral Home.
Aoraki area commander Inspector Dave Gaskin said Sutherland was well known, well respected, and well liked.
"He touched a lot of lives. He left his mark on everyone."
While it was "incredibly sad" Sutherland had died, he believed the keen outdoorsman would also have hated if his accident had left him "unable to live as he could previously".
The Givealittle page had raised $27,540 for the Sutherland family by yesterday afternoon.
